FIELD OF INVENTION

This utility model involves the field of temperature measuring device, especially an infrared thermometer for magnetic induction identification probe cap.

BACKGROUND OF INVENTION

Thermometer is an extremely common and frequently used kind of temperature measuring device. Under normal circumstances, one may feel sick when his/her body temperature exceeds 37.5° C., so many people deploy thermometers in their homes. With the advancement of technologies, a great many types of new thermometers have been developed. Electronic thermometer and infrared thermometer; by taking advantage of the identified relation between physical parameters (e.g. resistance, voltage, and current, etc.) of some substances and ambient temperature, electronic thermometer shows body temperature digitally, featuring clear readings and good portability. Its shortage lies in the fact that the accuracy of indicated value is affected by electronic elements and battery operation, etc. infrared thermometers include thermometers designed exclusively for ear temperature and solely for forehead temperature. Since the liquid in ear canals of users with otitis media may significantly impair the accuracy of IR ear thermometer, IR ear thermometer is not suitable for them. Where the room temperature is above 25° C. and below 20° C., IR forehead thermometer may frequently be affected by ambient temperature; for instance, sweating, fanning and air conditioning, etc. may affect the determined forehead temperature to a certain extent. For this reason, relevant technology development combines IR ear temperature and IR forehead temperature measurements in one infrared thermometer. Infrared thermometers designed for measurement of both ear temperature and forehead temperature are normally designed with removable caps for preventing faulty operation or supporting the automatic judgment mode. At present, the automatic induction & identification of cap is substantially realized in the following manner: Tact Switch or other devices are controlled for state switching after physical deformation; then, the cap is identified after MCU identification, as shown in FIG. 1 below; this scheme requires a lot of accessories, which make trouble in assembly; moreover, mechanical structure may frequently goes wrong.

CONTENT OF UTILITY MODEL

To make up for the defects of above-noted prior arts, this utility model offers an infrared thermometer for magnetic induction identification probe cap.

The technical scheme for this utility model: An infrared thermometer for magnetic induction identification probe cap, which is characterized by the fact that it includes the body of infrared theiiiiometer, at the upper end of which is a temperature probe designed with a cap, of which the inner side wall is beset with a magnet block; in the infrared thermometer body at lower end of temperature probe is a magnetic induction element connected with the main control unit of infrared thermometer body; when the said cap covers the temperature probe or is removed there-from, the magnetic induction between magnet block and magnetic induction element enables magnetic induction output control signal.

Further, the described body of infrared thermometer is applicable for measurement of forehead temperature and ear canal temperature, solely for forehead temperature measurement or solely for ear canal temperature measurement.

Further, the said magnetic induction element is a reed switch or Hall sensor.

The said magnetic induction output control signal includes magnetic induction output identification cap removal; the magnet block and magnetic induction element of cap performs induced output of startup control signal; when cap covers the temperature probe, the magnetic induction outputs power-off control signal; the magnetic induction identification output startup and power-off control signals are used for the infrared thermometer for forehead temperature measurement or ear canal temperature measurement.

The said magnetic induction output control signal includes the main control unit output forehead temperature measurement mode of infrared thermometer body identified by magnetic induction when the cap covers temperature probe; the main control unit output ear canal temperature measurement mode of infrared thermometer body based on the magnetic induction between magnet block on cap and magnetic induction element on infrared thermometer body; the switchover between magnetic induction identification output forehead temperature measurement mode and ear canal temperature measurement mode, which is applicable to infrared thermometer that is applicable for both forehead temperature measurement and ear canal temperature measurement.

The infrared thermometer with the mentioned technical solution of magnetic induction identification probe cap replaces common mechanical probe pin through magnetic induction identification output control signal, as shown in FIG. 1. By means of magnetic induction, the inner wall of cap is beset with magnet block, while corresponding magnetic induction elements are arranged in the body of infrared thermometer for concealed induction, which contributes to more concise appearance. The main control unit of infrared thermometer body controls startup and power-off through magnetic induction identification output so as to replace traditional startup and power-off keys. Magnetic induction identifies startup and power-off; this has application in infrared thermometers designed exclusively for forehead temperature measurement or ear canal temperature measurement. For the infrared thermometer applicable for both forehead temperature measurement and ear canal temperature measurement, the magnetic induction identification switches between the forehead temperature measurement and ear canal temperature measurement modes. Mode switching is needed because the built-in algorithm of forehead temperature measurement is different from that of ear canal temperature measurement. Magnetic induction identification cap is used to replace common mechanical probe pin. This technical solution is characterized by more efficient, easier operation and longer service life.
